2. Radar Does Not Rely on RF Signal Detection
As the threat landscape evolves and drones are more prevalent, security teams are realizing that drones can be disruptive to operations and safety, whether clueless, careless, or criminal. Unlike other limited technologies, radar detects everything that moves within the field of view.
Radio Frequency (RF) tools have been the primary drone detection method and for good reason. These tools scan the unlicensed spectrum where drones communicate with the operator, with many relying on a library of electronic capabilities for interdicting drone operation. In a market where one company, DJI, had 90+% share, and all communications is in unlicensed spectrum, interdicting drones is relatively straightforward.
The technology landscape evolves rapidly. There are dozens of drone manufacturers, each with new capabilities for niche markets. Communications options have matured for drone operators with choices outside any RF tool’s domain. Operators can turn to You Tube for guidance on shielding drones from these RF tools, using frequencies outside of the RF platform’s capabilities, or use licensed spectrum services where RF tools have no jurisdiction. Referred to as “dark” or “silent”, these drones are not detectable by RF tools.
Today, there are many options for masking or eliminating the electronic signal between operator and drone. The changes in how drones navigate the airspace make it difficult for yesterday’s favored solution to detect and track these drones.
Radar remains the obvious choice for detecting and tracking all movement in the airspace, regardless of communications or capabilities. Radar is the only sensor that detects all drones, 24/7.
